| Resonance Production in Heavy Ion Collisions: Suppression of $\Lambda(1520)$ and Enhancement of $\Sigma(1385)$ (2008) | |||||||||
Abstract | |||||||||
| We investigate the yield of $\Lambda(1520)$ resonance in heavy ion collisions within the framework of a kinetic master equation without the assumption of chemical equilibrium. We show that reactions such as $\Lambda(1520)+\pi \leftrightarrow \Sigma^*$ can favor $\Sigma^*$ production, thereby decreasing the $\Lambda(1520)$ yield. Within the same approach we thus find a yield enhancement for $\Sigma(1385)$ and a yield suppression for $\Lambda(1520)$..
